Description

Technical Field

[0001] This invention belongs to the field of blade assembly technology, and in particular relates to tooling for assembling segmented blades. Background Technology

[0002] With the rapid development of the wind power industry, larger blades have become the mainstream trend in blade development, significantly increasing transportation costs and difficulties. To reduce transportation difficulties and costs, blades are often cut into two sections during production and then assembled at the wind turbine installation site. Segmented blade assembly fixtures are used for the assembly of the blade root and tip sections. These fixtures can support and flexibly adjust the orientation angle of the root or tip section, allowing them to be assembled according to the designed blade shape. Due to the weight of the blades, high precision requirements for assembly, and the need for rapid assembly to meet production needs, segmented blade assembly fixtures must be able to achieve fast and accurate assembly under heavy loads, while also maintaining low cost and a long service life. In the existing technology, there are few tooling technologies involving segmented blade assembly (the closest technical solution: CN206280190U). The flexibility of blade orientation adjustment is poor, the adjustable dimensions are few, the adjustment range is small, the adjustment accuracy is low, the operation is not convenient, the overall tooling volume is large, the support area is small, and it is easy to become unbalanced. In order to keep the blade stable, the device needs to be very long, which is costly and cannot verify the docking effect. Summary of the Invention

[0003] In view of this, the present invention aims to propose a segmented blade assembly fixture to solve the problems of poor flexibility in blade orientation adjustment, limited adjustable dimensions, small adjustment range, low adjustment accuracy, poor ease of operation, large overall fixture volume, small support area, and easy imbalance.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] The segmented blade assembly fixture includes a blade root support fixture, a blade tip assembly fixture, and an auxiliary positioning device; the blade root support fixture and the blade tip assembly fixture are respectively installed at the blade root and blade tip.

[0006] The blade tip assembly fixture includes several support and adjustment devices; these devices are evenly distributed below the blade tip.

[0007] The auxiliary positioning device is installed on the blade tip assembly fixture and the blade root support fixture.

[0008] Furthermore, the support adjustment device includes a rotating tray assembly, a lifting mechanism, a chordal movement mechanism, and an axial movement mechanism;

[0009] The rotating pallet assembly, lifting mechanism, chordal movement mechanism, and axial movement mechanism are arranged sequentially from top to bottom; the bottom of the axial movement mechanism is equipped with casters around its perimeter.

[0010] The swivel wheel is equipped with a handbrake, and the bottom of the axial movement mechanism is provided with an anti-tipping support column, the height of which is less than the height of the swivel wheel.

[0011] Furthermore, the rotating pallet assembly includes a rotating lifting component, a rotating pallet, and a support portion; the rotating lifting component is positioned above the lifting mechanism, the rotating pallet is positioned on the upper part of the rotating lifting component, and the support portion is positioned on the rotating pallet; the rotating lifting component can drive the support portion to move up and down, the support portion can be adjusted left and right, and the shape of the upper surface of the support portion corresponds to the shape of the bottom of the blade.

[0012] Preferably, the rotating lifting component includes a rotating shaft, adjusting bolts, and a pallet base. The pallet base is positioned above the lifting mechanism, and the rotating shaft is positioned on both sides of the pallet base. The rotating pallet and the rotating pallet are movably connected through the rotating shaft. The support part is positioned above the rotating pallet. The rotating pallet has a first threaded hole around its perimeter, and the pallet base has a second threaded hole corresponding to the first threaded hole around its perimeter.

[0013] The shape of the upper surface of the support corresponds to the shape of the blade's bottom. The upper surface of the support is a conforming surface that follows the blade's shape. The rotating shaft is located below the support and parallel to the axial direction of the conforming surface. The support is rotatably mounted above the lifting mechanism via the rotating shaft. There are four adjusting bolts, located at the four corners of the support and threadedly connected to it. The lower ends of the adjusting bolts are located on the upper surface of the lifting mechanism. By adjusting the four corner adjusting bolts, the fixture rotates around the rotating shaft, thereby adjusting the blade's chord angle. If the blade needs to rotate to one side, simultaneously tighten the two bolts on that side downwards and the other two upwards. By rotating the shaft, this device supports the blade's angle, and in conjunction with the adjusting bolts, precise angle adjustment can be achieved under high loads. The device is low-cost, has a long service life, and is easy to operate.

[0014] Preferably, the rotating lifting component includes a lifting rotating cylinder and a rotating base plate. The rotating base plate is mounted on the lifting assembly, and the bottom of the lifting rotating cylinder is rotatably mounted on the lifting assembly. The output end of the lifting rotating cylinder is connected to the rotating base plate.

[0015] Furthermore, the lifting mechanism includes a lifting device, a lifting support column, and a lifting base frame.

[0016] The lifting base is positioned above the chordally moving mechanism;

[0020] Furthermore, the chordal movement mechanism includes a chordal base frame, and chordal slide rod mounting posts and chordal adjusting bolt mounting posts are provided at the four corners of the chordal base frame;

[0021] The front and rear sides of the chordal base frame are equipped with chordal slide rods via chordal slide rod mounting columns. Each chordal slide rod is equipped with two chordal sliders. A lifting mechanism is supported on the chordal sliders. A chordal adjusting bolt is threaded on the chordal adjusting bolt mounting column. The chordal adjusting bolt is parallel to the chordal slide rod, and one end of the chordal adjusting bolt abuts against the side of the lifting support column.

[0022] The end of the support adjustment device is equipped with a chord adjustment bolt handwheel.

[0023] Furthermore, the axial movement mechanism includes an axial base frame, with casters positioned below the four corners of the axial base frame;

[0024] The axial base frame is equipped with axial slide rod mounting columns on all four sides above, and axial slide rods are installed on both sides of the axial base frame via the axial slide rod mounting columns. Each axial slide rod is equipped with two axial sliders. The chordal base frame is located below the axial sliders.

[0025] An axial adjusting bolt is threaded onto the axial slide bar mounting post; the axial adjusting bolt is parallel to the axial slide bar.

[0026] One end of the axial adjusting bolt abuts against the side of the chordal sliding rod mounting post;

[0027] An axial adjustment bolt handwheel is provided on the side of the axial adjustment bolt away from the chordal slide rod mounting column; the chordal translation mechanism and the axial translation mechanism move the upper component along the slide rail by rotating the axial adjustment bolt handwheel and the chordal adjustment bolt handwheel, thereby realizing the chordal / axial translation of the upper component and thus realizing the adjustment of the chordal / axial position of the blade.

[0028] Furthermore, the number of support adjustment fixtures is at least two. The two support adjustment fixtures support the blade tip segment at a set axial position. After the blade tip segment is placed on the two support adjustment fixtures at the set axial position, the chordal angle of the blade tip segment is adjusted by rotating the tray; the height of the blade tip segment is adjusted by a lifting mechanism, and the axial angle of the blade tip segment can be adjusted by adjusting the relative height of the two support adjustment fixtures; the position of the support adjustment fixtures is adjusted by universal wheels for coarse adjustment, and fine adjustment is performed in conjunction with the chordal translation mechanism and the axial translation mechanism, achieving a wide range and high precision of position and angle adjustment to meet production needs. In other words, the blade tip segment assembly fixture of this invention can achieve position adjustment in the chordal, axial, and height directions of the blade tip segment, as well as angle adjustment, with multiple adjustment dimensions, a large range, and high precision, thereby achieving precise docking of segmented blades.

[0029] Furthermore, the auxiliary positioning device includes a first docking laser assembly and a second docking laser assembly;

[0030] The first docking laser assembly includes a first laser transmitter and a first laser receiver;

[0031] Several first laser emitters are mounted on the support and adjustment device, and several first laser receivers corresponding to the first laser generators are mounted on adjacent support and adjustment devices.

[0032] The second docking laser assembly includes a second laser emitter and a second laser receiver. Several second laser emitters are arranged on the side of the blade root section support fixture near the support adjustment device, and the second laser receivers corresponding to the second laser emitters are arranged on the support adjustment device.

[0033] Preferably, the number of first laser emitters is three;

[0034] The number of second laser emitters is 3;

[0035] Three docking lasers are set on a support and adjustment fixture near the blade root section in the blade tip assembly fixture; the positions of the three docking indicator plates are set to correspond to the positions of the docking lasers.

[0036] The docking indicator plate is equipped with indicator marks. The indicator laser emitted by the docking laser shines on the docking indicator plate. The orientation of the blade tip is adjusted according to the position of the laser on the docking indicator plate. When the laser emitted by the three lasers shines on the marked position on the docking indicator plate, the blade orientation meets the docking requirements. If the axial spacing meets the requirements, the subsequent connection work between the blade root section and the blade tip section can be carried out.

[0037] Furthermore, it also includes several mating pin assemblies, each comprising two sleeves and a bushing;

[0038] Two sleeves are set on both sides of the sleeve shaft. Before the blade is cut, the shaft is inserted into the two sleeves and the two sleeves are bonded to both sides of the cutting surface. The sleeves are set at the leading edge, trailing edge and beam cap area respectively. After curing, the shaft is pulled out and the blade is cut. When the blade is subsequently connected, the shaft is inserted into the sleeve. If all three shafts can be fully inserted into the sleeve, it proves that the precise connection has been completed.

[0039] Compared with existing technologies, the segmented blade assembly fixture of the present invention has the following advantages:

[0040] The tooling structure of this application is simple, low-cost, easy to operate, has good docking effect, and is highly efficient. It can meet the requirements of heavy load and high adjustment accuracy when docking segmented blades.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0052] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] like Figures 1 to 3 As shown, the segmented blade assembly fixture includes a blade root support fixture, a blade tip assembly fixture, and an auxiliary positioning device. The blade root support fixture and the blade tip assembly fixture are respectively installed at the blade root and blade tip. The blade tip assembly fixture includes several support adjustment devices. The several support adjustment devices are evenly installed below the blade tip. The auxiliary positioning device is installed on the blade tip assembly fixture and the blade root support fixture.

[0054] The support adjustment device includes a rotating tray assembly, a lifting mechanism, a chordal movement mechanism, and an axial movement mechanism; the rotating tray assembly, lifting mechanism, chordal movement mechanism, and axial movement mechanism are arranged sequentially from top to bottom; the bottom of the axial movement mechanism is equipped with casters 16.

[0055] The caster wheel 16 is a caster wheel 16 with a handbrake. The bottom of the axial movement mechanism is provided with an anti-tipping support column, the height of which is less than the height of the caster wheel 16.

The rotating pallet 1 has a first threaded hole around its perimeter, and the pallet base 5 has a second threaded hole around its perimeter corresponding to the first threaded hole.

[0058] The upper surface of the support part 2 is a conforming surface that follows the shape of the blade. The rotating shaft 3 is located below the support part 2 and parallel to the axial direction of the conforming surface. The support part 2 is rotatably mounted above the lifting mechanism via the rotating shaft 3. There are four adjusting bolts 4, which are respectively located at the four corners of the support part 2 and threadedly connected to the support part 2. The lower ends of the adjusting bolts 4 are located on the upper surface of the lifting mechanism. By adjusting the four corner adjusting bolts 4, the fixture is rotated around the rotating shaft 3, thereby adjusting the chord angle of the blade. If the blade needs to be rotated to one side, the two bolts on that side are tightened downwards and the other two bolts are tightened upwards simultaneously. By rotating the rotating shaft 3 to support the blade angle, and in conjunction with the adjusting bolts 4, precise angle adjustment can be achieved under high load conditions. The device is low in cost, has a long service life, and is easy to operate.

[0059] The rotating lifting component includes a lifting rotating cylinder and a rotating base plate. The rotating base plate is mounted on the lifting assembly, and the bottom of the lifting rotating cylinder is rotatably mounted on the lifting assembly. The output end of the lifting rotating cylinder is connected to the rotating base plate.

[0063] The axial movement mechanism includes an axial base frame 15, with casters 16 positioned below the four corners of the axial base frame 15. Axial slide rod mounting columns 17 are provided on the upper perimeter of the axial base frame 15, and axial slide rods 18 are mounted on both sides of the axial base frame 15 via the axial slide rod mounting columns 17. Each axial slide rod 18 has two axial sliders 19. A chordal base frame 9 is positioned below the axial sliders 19. Axial adjusting bolts 23 are threaded onto the axial slide rod mounting columns 17. The axial adjusting bolts 23 are parallel to the axial slide rods 18. One end of the axial adjusting bolt 23 abuts against the side of the chordal slide rod mounting column 10. An axial adjusting bolt handwheel 20 is located on the side of the axial adjusting bolt 23 away from the chordal slide rod mounting column 10. The chordal translation mechanism and the axial translation mechanism move the upper component along the slide rail by rotating the axial adjusting bolt handwheel 20 and the chordal adjusting bolt handwheel 13, thereby achieving chordal / axial translation of the upper component and adjusting the chordal / axial position of the blade.

[0064] The number of support and adjustment fixtures is at least two. The two support and adjustment fixtures support the blade tip segment at a set axial position. After the blade tip segment is placed on the two support and adjustment fixtures at the set axial position, the chordal angle of the blade tip segment is adjusted by rotating tray 1; the height of the blade tip segment is adjusted by a lifting mechanism, and the axial angle of the blade tip segment can be adjusted by adjusting the relative height of the two support and adjustment fixtures; the position of the support and adjustment fixtures is adjusted by casters 16 for coarse adjustment, and fine adjustment is performed in conjunction with chordal and axial translation mechanisms, achieving a wide range and high precision in position and angle adjustment to meet production needs. In other words, the blade tip segment assembly fixture of this invention can achieve position adjustment in the chordal, axial, and height directions of the blade tip segment, as well as angle adjustment, with multiple adjustment dimensions, a large range, and high precision, thereby achieving precise docking of segmented blades.

[0065] The auxiliary positioning device includes a first docking laser assembly and a second docking laser assembly;

[0066] The first docking laser assembly includes a first laser transmitter 27 and a first laser receiver;

[0070] The number of second laser emitters 28 is 3.

[0071] There are two sets of lasers and indicator plates, three in each set. One set of lasers for the blade tip is used to position the blade tip and prevent the blade tip itself from deforming (the blade tip is tens of meters long and has a relatively thin wall, making it easy to bend and deform). The lasers and indicator plates for the blade tip and blade root are used for blade docking to ensure precise blade docking.

[0072] The docking indicator plate is equipped with indicator marks. The indicator laser emitted by the docking laser shines on the docking indicator plate. The orientation of the blade tip is adjusted according to the position of the laser on the docking indicator plate. When the laser emitted by the three lasers shines on the marked position on the docking indicator plate, the blade orientation meets the docking requirements. If the axial spacing meets the requirements, the subsequent connection work between the blade root section and the blade tip section can be carried out.

[0073] It also includes several docking pin assemblies, each consisting of two sleeves 21 and a sleeve shaft 22. The two sleeves 21 are located on both sides of the sleeve shaft 22. Before blade cutting, the shaft is inserted into the two sleeves 21, and the two sleeves 21 are bonded to both sides of the cutting surface. The sleeves 21 are located at the leading edge, trailing edge, and beam cap area, respectively. After curing, the shaft is pulled out, and the blade is cut. When the blade is subsequently docked, the shaft is inserted into the sleeves 21. If all three shafts can be fully inserted into the sleeves 21, it proves that the precise docking has been completed.

[0074] The blade root support fixture includes a base and a blade root support, with the blade root support mounted on the base; the shape of the top of the blade root support corresponds to the shape of the blade root.

[0075] The blade root assembly fixture can use existing blade support fixtures for support, without the need for orientation adjustment; the blade tip assembly fixture supports the blade tip and adjusts its orientation; the mating pin is a positioning pin used for positioning when the blade root and blade tip are mated. In terms of fixture application, the blade root assembly fixture can be orientation-adjustable, while the blade tip assembly fixture only provides support, or both the blade root and blade tip assembly fixtures can be orientation-adjustable.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
